PayPal now has a page that shows special local deals that are available, similar to Groupon. And when you are checking out, you can switch between debit cards and credit cards that you've stored on PayPal wallet. Adding new cards is as easy as snapping a picture of the credit card you want to put in your PayPal wallet.
Keep track of your PayPal balance and transfer money in and out of your PayPal account, even if the the other side to a transaction isn't even a member. To do that, merely send the other person a message using an email address or mobile phone number, with the dollar amount you are sending or requesting. Also, you can now finance a PayPal purchase by using the Bill Me Later option, offered inside the app.
If you already have the PayPal app on your phone, you should have been notified about the update. Otherwise, it is a free download from the Google Play Store and Apple App Store.
